         4.1. DUTIES AND RESPONSIBILITIES OF THE ESCROW AGENT. The Escrow
Agent's duties and responsibilities shall be subject to the following terms and
conditions:

                  (a) The Subscriber and Company acknowledge and agree that the

acting upon any written notice, instruction, instrument, statement, request or

faith to be genuine and to have been signed or presented by the proper person or
party, without being required to determine the authenticity or correctness of

authorized to give notice or make any statement or execute any document in

complete authorization and protection in respect of any action taken, suffered
or omitted by Escrow Agent hereunder in good faith and in accordance with the
opinion of such counsel.

                  (b) The Subscriber and Company acknowledge that the Escrow
Agent is acting solely as a stakeholder at their request and that the Escrow
Agent shall not be liable for any action taken by Escrow Agent in good faith and
believed by Escrow Agent to be authorized or within the rights or powers

jointly and severally, agree to indemnify and hold harmless the Escrow Agent and
any of Escrow Agent's partners, employees, agents and representatives for any
action taken or omitted to be taken by Escrow Agent or any of them hereunder,
including the fees of outside counsel and other costs and expenses of defending
itself against any claim or liability under this Agreement, except in the case

specified in such notice, the Subscriber and Company will issue to the Escrow

Documents and Subscriber Documents with the clerk of any such court.


<PAGE>

                  (e) The Escrow Agent does not have and will not have any
interest in the Company Documents and Subscriber Documents, but is serving only

liable for any loss resulting from the making or retention of any investment in
accordance with this Escrow Agreement.

                  (f) This Agreement sets forth exclusively the duties of the
Escrow Agent with respect to any and all matters pertinent thereto and no
implied duties or obligations shall be read into this Agreement.

                  (g) The Escrow Agent shall be permitted to act as counsel for
the Subscriber in any dispute as to the disposition of the Company Documents and
Subscriber Documents, in any other dispute between the Subscriber and Company,
whether or not the Escrow Agent is then holding the Company Documents and
Subscriber Documents and continues to act as the Escrow Agent hereunder.

                  (h) The provisions of this Section 4.1 shall survive the
resignation of the Escrow Agent or the termination of this Agreement.

         4.2. DISPUTE RESOLUTION: JUDGMENTS. Resolution of disputes arising
under this Agreement shall be subject to the following terms and conditions:

                  (a) If any dispute shall arise with respect to the delivery,
ownership, right of possession or disposition of the Company Documents and
Subscriber Documents, or if the Escrow Agent shall in good faith be uncertain as
to its duties or rights hereunder, the Escrow Agent shall be authorized, without
liability to anyone, to (i) refrain from taking any action other than to
continue to hold the Company Documents and Subscriber Documents pending receipt
of a Joint Instruction from the Subscriber and Company, or (ii) deposit the
Company Documents and Subscriber Documents with any court of competent
jurisdiction in the State of New York, in which event the Escrow Agent shall
give written notice thereof to the Subscriber and the Company and shall
thereupon be relieved and discharged from all further obligations pursuant to
this Agreement. The Escrow Agent may, but shall be under no duty to, institute
or defend any legal proceedings which relate to the Company Documents and
Subscriber Documents. The Escrow Agent shall have the right to retain counsel if
it becomes involved in any disagreement, dispute or litigation on account of
this Agreement or otherwise determines that it is necessary to consult counsel.

                  (b) The Escrow Agent is hereby expressly authorized to comply
with and obey any Court Order. In case the Escrow Agent obeys or complies with a
Court Order, the Escrow Agent shall not be liable to the Subscriber and Company
